qsvdec: do not sync PIX_FMT_QSV surfaces

Browse Source 
Introducing enforced sync points in arbitrary places is bad for
performance. Since the vast majority of receiving code (QSV VPP or
encoders, retrieving frames through hwcontext) will do the syncing, this
change should not be visible to most callers. But bumping micro just in
case.

This is also consistent with what VAAPI hwaccel does.
